SPINNING-BOBBIN.

H'" I l Specification of Letters Patent No. 19,647, dated March 16, 1858.

To 'all whom it may concern:

Be it known that I, ALFRED E. NICHOLS, of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Self-Packing Bobbin; and I hereby declare that the following specification, in c onnection with the accompanying drawing and references thereon, constitutes a lucid, clear, and exact description of the construction and use of the same.

In referring to the said drawings, Figure l. denotes a plan or top view. Fig. 2. an elevation of the same. Fig. 3. a vert-ical section, on line A, B, Fig. l. vertical section on line C, D, of Fig. l, showing one entire side of the slot, formed in the bobbin..

Invention The nature of my invention consists in so slotting the bobbin, for a portion only of its length, in the manner described, that this portion may yield to impart a constant, uniform, or desired untrammeled adherence to the spindle, while the remaining portion is solid or rigid for receiving and carrying the yarn, and allowing it to be entirely used therefrom without either affecting the uniform tension of the yarn thereon, or the uniform adherence of the bobbin to the spindle. And in providing the slotted portion of the bobbin with a spring, for increasing its adherence to the spindle, all as hereafter seen.

Construction: To enable persons skilled in the art to which my invention appertains, to construct and carry out the same, I will describe it as follows:

A spindle may be made use of; seen at A, in the several figures of the drawing, the spindle pulley thereon, if one be used, being seen at B.

I construct the bobbin as seen at C, or of other desired shape, and form a slot in and through a portion of its length, while the remaining part must be left solid and rigid, to carry the yarn in such manner as not to trammel the adherence of the bobbin to the spindle. The slot being seen at E, which divides the bobbin in such manner as to allow each of the divisions so made to yield and adhere to the spindle, as the bobbin is Fig. 4;. 1s a crowded thereon; to prevent its slipping when so placed in its working position on the spindle; by the'surfaces G, of the hole in the bobbin coming in contact with the spindle with sufficient force to eifectually hold it thereon, when in operation, by reason of a part of the length of the bobbin being slotted; and the remaining part being necessarily left solid, in order to carry the yarn, and more eectually apply the spring or elasticity of the bobbin to the desired purpose. Thus by slotting the bobbin, in the manner described, it possesses the inherent quality within itself of adhering with suliicient power to the spindle when placed properly thereon.

In cases where the bobbin is to be used severely, and consequently needing an increased power to hold it on the spindle, beyond that which would rordinarily be had of the slotted part of the bobbin itself, I form a groove around and into the bobbin as seen at F, and then construct a spring ring seen at D, or an equivalent of it, and open and spring it into this groove F, and by the centripetal action of it, the divisions of the bobbin, caused by its slotting, are brought together against the spindle with an increased power, to elfect-ually hold it thereon.

When my bobbin be used, no preparation whatever of the spindle is necessary to holdv it thereon, but it is rendered self packing or holding by its novel and peculiar eonstruc tion, and it is made at very little expense.

UsezAll that is necessary to do in using my invention, or bobbin, is to crowd it upon the bare spindle sufficiently for it to remain thereon when in use, in the manner before described.

That I claim as my invention, and desire to secure by Letters Patent, is

A slotted bobbin having a spring ring or its equivalent so applied to it as to impart increased adherence of the slotted portion to the spindle on which it is placed, essentially in the manner and for the purposes fully set forth and described.
